Free Stem Splitter

Free stem splitter online. A stem splitter separates a finished song into its parts so you can remix, sample, practise, or make a karaoke track. This free online stem splitter produces two stems from a stereo file: an instrumental with the vocals reduced, and an acapella estimate that emphasises the vocal. Preview each one and download it as a WAV.

It runs in your browser, so your track is processed on your device and never uploaded.

The tool uses the stereo image to separate parts. Subtracting the channels cancels center panned content, which gives the instrumental. Summing the channels emphasises the center, which gives the vocal estimate. It is fast, private, and free.

Because it relies on stereo placement rather than a trained AI model, the split is an approximation. Center panned instruments can bleed between stems, and a mono file cannot be split. For studio grade four stem separation of drums, bass, vocals, and other parts, a dedicated AI service goes further. This tool covers the common vocal and instrumental split instantly.

If you want stems you fully own and control, generating a song from scratch beats splitting an existing one. InstaSong creates original tracks, with or without vocals, in the style you choose, so you avoid copyright issues and bleed between parts.

It is free to start with credits included, which is a fast way to get clean, original material for your project.
